'Umar bin Al-Khattab (May Allah be pleased with him) reported: The Messenger of Allah (PBUH) said, "Whoever of you performs Wudu' carefully and then affirms: 'Ash-hadu an la ilaha illallahu Wahdahu la sharika Lahu, wa ash-hadu anna Muhammadan 'abduhu wa Rasuluhu [I testify that there so no true god except Allah Alone, Who has no partners and that Muhammad ((PBUH) is His slave and Messenger],' the eight gates of Jannah are opened for him. He may enter through whichever of these gates he desires (to enter)."
